Upper roadway closed at McGhee Tyson airport

Construction at McGhee Tyson Airport could cause detours for travelers.

Friday, crews began removing some of the stone on the front of the terminal building. They're taking it off to pinpoint the source of water leaks and look for any structural damage.

The work is expected to take three weeks. During that time, the upper road, which is the departures level, will be closed. Travelers will have to enter the building on the first floor.

"We have moved our curbside check-in to that lower level so all the services they would have received here on this upper roadway are going to be available down on the first roadway as well," said Becky Huckaby, airport spokesperson.

During the temporary construction, passengers are asked to arrive one-and-a-half hours before a domestic flight and two-and-a-half hours before an international flight.
